Summary:
A pale brownish toadfish becoming white below with the upper part of the body mottled with small irregular white spots, and no dark lateral stripe or vertical bars below the eyes. The Yelloweye Toadfish is covered in well-developed spines projecting from short papillae which continue along the upper lateral line to the caudal fin base.

More Info


Distribution

Southwest of Shark Bay to North West Cape, Western Australia, the Timor Sea north-west of Darwin, and the Great Barrier Reef to off Dunk Island, and reefs in the Coral Sea, Queensland. 

Features

Dorsal fin 9; Anal fin 6; Pectoral fin 16; Caudal fin 11.
Body elongate, rounded dorsally and flattened ventrally, tapering to a narrow caudal peduncle; head length 2.6 in SL; snout to anterior of vent 1.4 in SL, to origin of dorsal fin 1.5 in SL, to origin of anal fin 1.4 in SL, to origin of pectoral fin 2.4 in SL; width at base of pectoral fin 3.2 in SL; depth from dorsal fin origin to anal fin origin 5.1 in SL; depth at posterior of dorsal fin 7.6 in SL; caudal peduncle length 4.6 in SL; least depth of caudal peduncle 15.3 in SL. 
Ventrolateral skin fold extending from behind pectoral-fin margin to caudal fin; lateral line indistinct, with small associated papillae, traces only on head, lines more discernable on mid-lateral and ventrolateral parts of caudal peduncle, extending to caudal fin base; upper lateral line on caudal peduncle associated with a double row of small papillae extending from the main spinous covering to the caudal fin base and each containing a small, though well-developed spine; no well-developed papillae along distal portion of lower lateral line, but a row of small spines persists to caudal fin base; body spines 2-rooted, moderately dense, strongly developed and project from short, narrow papillae, extend dorsally from level of nasal organs, through a narrow interorbital band, to either side of dorsal fin base, extended dorsolaterally under dorsal fin to meet papillae along upper lateral line, extended laterally from beneath nasal organ to dorsal fin base, extend ventrally from behind chin almost to vent; spines on cheek only moderately dense, scarcely extend over prebanchial margin. 

Similar Species

T. parcuspinus appears to be most similar to T. squamicauda in having a double row of spine-enveloping papillae following the upper lateral line on the caudal peduncle. There is a notable lack however, of well-developed papillae along the distal portion of the lower lateral line in T. parcuspinus, whereas these are strongly developed in T. squamicauda, and have in association the bulk of vestigeal spines present on the peduncle in that species. Nevertheless, a row of small spines follows the lower lateral line to the caudal fin base in T. parcuspinus. The apparent immaturity of the single specimen of T. parcuspinus inhibits extensive discussion of colour pattern, but there is no indication at least, of any development of a strong, dark lateral stripe. The dorsal and lateral spination of T. squamicauda is much more dense than in T. parcupsinus, and spinous overlapping of the prebranchial margin almost entirely limited to the former species. 

Etymology

The specific name parcuspinus refers to the sparse spination of this species, in contrast to the relatively dense spination of the superficially similar Torquigener squamicauda
